Using the image above, why is the solution on the far right considered the most concentrated?

• It has the least amount of solvent.

• It has the most amount of solute.

• It has the least amount of solute.

• It has the most amount of solvent.

Which of the following explanations would make a solution more dilute?

• Add more solvent

• Add more solute

• Remove solvent

• Add equal amounts of solvent and solute

A solution is said to be concentrated, when the proportion of solute in a solution is high compared to the volume of the solvent, making the solution?

• Weaker

• Dilute

• Stronger

• Sweeter

True or False: A solution is said to be dilute, when the proportion of solute in a solution is low compared to the volume of the solvent, making the solution thinner and weaker.

• True

• False

Which of the following would best describe a saturated solution?

• Has a lot of solute in it.

• Has very little solute in it.

• Has a maximum amount of solute in it.

• Has no solute in it.

True or False: A supersaturated solution is unable to absorb any more solute and the remainder of the solute is left undissolved at the bottom of the container.

• True

• False

When comparing a dilute, concentrated, and saturated aqueous solution mixed with blue Kool Aid, which of the following would be true of a saturated solution?

• It would be the lightest of the three solutions.

• It would be the strongest of the three solutions.

• It would be somewhat dark, but not the darkest in color.

• It would not be able to absorb any more Kool Aid powder.

• It would be the weakest of the three solutions.
